Like a slice of pizza, a curvature could give fish fins their strength
May 31, 2017 11:21 AM - Brown University

Pizza enthusiasts know well that a simple u-shaped curvature at the crust can keep a thin slice from drooping over when lifted from a plate. A team of engineers from Brown University has shown that fish may take advantage of roughly the same dynamics to stiffen their fins for swimming.

Research by PhD candidate Nicola Bryson-Morrison from the School of Anthropology and Conservation (SAC) suggests chimpanzees are aware of the risks of foraging too close to humans.

Roaming Bison Get Caught in Crossfire
May 29, 2017 10:20 AM - University of Guelph

There’s safety in numbers for herd animals, but not if some members of the herd make poor decisions. That was one of the findings of research by  U of G integrative biology professor John Fryxell and U of G graduate Daniel Fortin, now a biology professor at Université Laval.

They studied the movement patterns of bison in Prince Albert National Park in Saskatchewan and found that those animals that ventured outside the park into neighbouring farmland were hunted, which contributed to the herd’s population decline over a nine-year period from 2005 to 2013.

University of Saskatchewan Bat Men shed light on bat super immunity
May 26, 2017 07:40 AM - University of Saskatchewan

Coronaviruses such as Severe Acute Respiratory Syndrome (SARS) and Middle-East Respiratory Syndrome (MERS) cause serious and often fatal disease in people, but bats seem unharmed.

Veterinary microbiology PhD candidate Arinjay Banerjee and his professor Vikram Misra have now found some clues.

Wolves need space to roam to control expanding coyote populations
May 24, 2017 08:16 AM - University of Washington

Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded to the detriment of a balanced ecosystem.

That’s the main finding of a study appearing May 23 in Nature Communications that analyzed the relationship between top predators on three different continents and the next-in-line predators they eat and compete with. The results were similar across continents, showing that as top predators’ ranges were cut back and fragmented, they were no longer able to control smaller predators.

Raising Coral
May 17, 2017 08:21 AM - Oregon State University

Imagine you’re swimming lazily along, just below the water’s surface in a tropical ocean. You look down at a colorful array of pinks, yellows and greens. Spikey corals cover the floor below. Small fish swim in and out of hiding places, ducking behind the stationary animals to avoid your peering eyes.

Super hearing: University of Toronto scientists study fly to develop better hearing aids
May 17, 2017 08:21 AM - University of Toronto

Ormia ochracea's sense of directional hearing is second to none in the animal kingdom.

“These flies have highly specialized ears that provide the most acute directional hearing of any animal,” says Andrew Mason, an associate professor of biology at U of T Scarborough.  “The mechanism that makes their hearing so exceptional has even led to a range of bio-inspired technology, like the mini-directional microphones used in hearing aids.”

Rare Footage Helps Explain What Narwhals Use Their Tusks For
May 17, 2017 07:18 AM - Alicia Graef, Care2

Scientists are marveling over never-before-seen footage of narwhals that has brought to light new evidence for what those unicorn-like tusks are actually used for.
